Hallo SIESTA users!

I have run my fdf to get the band structure for graphene and TIO2 Rutile.
I have made the visualization using gnubands and gnuplot. But then, I got
soo many lines. Can anyone informs me why it can be happened? is there
any mistake?
I trie to attach that picture, but it is difficult.

And another things that I want to ask is, how to label the x-axis so that
we get the symmetry label on that (ex. Gamma, M, K etc.)

I have attached the file of bands structure visualization
and here the K-point for graphene
%block Bandlines
1  -0.500   0.000  0.000 M
25  0.000   0.000  0.000 \Gamma
25  0.3329 -0.6658 0.000 K
%endblock BandLines

while for tio2 (rutile, space group 136)
%block Bandlines
1  0.000 0.000 0.000 \Gamma
20 0.000 0.500 0.000 X
25 0.000 0.500 0.500 R
20 0.000 0.000 0.500 Z
25 0.000 0.000 0.000 \Gamma
20 0.500 0.500 0.000 M
25 0.500 0.500 0.500 A
20 0.000 0.000 0.500 Z
%endblock BandLines

Thank you,
